Summary:
Last week the students completed section 1 and section 2 of chapter 1 and performed a lab experiment on Friday. They have learned about position and location, speed and velocity, distance time graphs, and speed = distance/time. They have studied these topics through power points, review worksheets, practice class and homework problems, and lab experimentation. Today, I am going to begin section 3 and introduce them to acceleration. I am going to teach the students what acceleration is and the formula to use when calculating acceleration using velocity and time. However, before I begin teaching about acceleration I am going to conduct a short 3 minute warm up review on the information we learned this week. This is going to be done through the "true and false" worksheet that I will have previously made up. Each student will be given a "Section 1 and 2: True or False" handout which will later act as a great study aid. I will simply read through the statements and after each one ask for a volunteer to tell me whether it is true or false and if it is false to correct it. (I might even have a reward for volunteering such as blow pops, tootsie rolls, skittles, etc.) After the warm-up review I will jump right into the power point notes. After the notes, I will be working with the class as a whole on the "Calculating Acceleration" problem on page 28. After I go through this problem with the students and teach them how to pick out the important information in the word problem and use the acceleration formula I will instruct them to try the "Practice the Math" part b problems on their own or with a partner. This class work will take up the remainder of the class period. The homework "Chapter 1 Math Practice" will be assigned with about five minutes left in the class period. I will inform the class that tomorrow they will be doing another fun lab with marbles and stopwatches to study the relationship between acceleration and slope.
Objectives:
Students will be able to explain how acceleration is related to velocity through question and answer.
Students will be able to calculate acceleration through practice with solving equations and word problems.
Materials:
Pen/pencil
Notebook
Textbook
Calculators
Section 1 and 2: True or False Handout
Chapter 1 "Math Practice" worksheet (pg. 53 in workbook)
Instruction: Opening
Since today is Monday and the students are just getting back into the grind after the weekend I decided to start today's class with a short 3-5 minute warm-up review. I will quickly pass out the handout I made up this weekend of statements that are either true or false. These statements will consist of information from section 1 and section 2 that I want to refresh in the students minds. I will read the question aloud to the class and ask for a volunteer to tell me whether the statement is true or false, and if it is false to correct it. This is simply to get the students minds thinking and in "science mode".

After the warm-up review, I will set the power point up and instruct the students to take out their notebooks and get ready to take notes on section 1.3. The power point will consist of notes on the first half of section 1.3 (acceleration and calculating it). The power point will consist of the important terms, concepts, and formulas that I wish for the students to master.
After the power point, I will work with the class as a whole on a practice problem of calculating acceleration. The students will be instructed to open their textbooks to page 28 and copy down the sample problem in their notebooks. This problem will already be written on the board at the front of the room. When the students are done writing, I will work with the class on how to read and solve this type of problem. I will ask them questions such as: What do you know? What do you want to find out? Write the formula out. How do you substitute into the formula?
My goal is not to solve the calculation problem for them, but it is to teach them how to do it on their own. After I have worked through this problem with the students, I will instruct them to now try the "Practice the Math", or part b, on their own. They may work individually or with a partner, but are to each show their own work and on a blank piece of paper because it will be handed it to me. They will be informed that this is not their homework, it is class work. Therefore, they should use their time wisely because whatever they do not finish they will have to complete at home on top of what I will be assigning for homework. I will be walking around to each student or group to make sure everyone is on task and to be available if any one needs my assistance.
Closing
With about five minutes left in the class, I will hand out the Chapter 1 "Math Practice" homework worksheet on calculating acceleration. I will tell the students that they will need to turn this in at the beginning of class tomorrow along with the two practice problems they were working on today in class.
Assessment
The Chapter 1 "Math Practice" homework assignment tonight is the assessment for today's lesson. It directly assesses the students understanding on how to use velocity and time in calculating acceleration. It requires the students to calculate acceleration from both equations and short word problems. This will be collected at the beginning of class tomorrow and will count as a homework grade. I want to make sure the students have a strong and clear understanding on how to use this formula because tomorrow they will be working in lab groups to experiment with acceleration and slope and how the two relate.
